Hi,

Welcome to the forums.

Sorry if it sounds like a bit of a downer but ...

There isn't a specific set-up tutorial, but the set up is all pretty similar so you can search the forum for set up advice of the UHD722 or HD621 with any of the Meridian surround processors.
Not sure why there would be a 3rd party manual, but I'd recommend that you do have a good read at the manuals.
I wouldn't describe the G65 display as 'tiny' but the configuration wizard is all explained from P43 of the manual.
Yes, you can do the set up via a windows computer which is described on P53 of the manual.
There is room correction but that's in another manual and you'll need to supply a microphone (similar to the old Radio Shack one) for calibration (P55 of the manual).

You haven't mentioned any speakers, so it would be useful to know if you're using Meridian DSP speakers or not.

Meridian stuff isn't simple plug and play but a good read at the manuals will hopefully get you going.

Brian
